Product details

Overview

PHPT61010NYX from Nexperia is an AEC-Q101-qualified NPN high-power bipolar transistor in LFPAK56 (SOT669) package, rated for 100 V V_CEO, 10 A continuous collector current, and 175 °C junction temperature. It delivers 25–37 mΩ R_CEsat at I_C = 10 A / I_B = 1 A, enabling high-efficiency load switching in automotive motor drives and linear regulators.

For engineers reviewing the PHPT61010NYX datasheet, PHPT61010NYX pinout, PHPT61010NYX application, or PHPT61010NYX equivalent, this device supports thermally demanding power management roles where low saturation resistance, robust thermal derating, and automotive-grade reliability are required.

Technical Context

This NPN bipolar transistor operates in linear or saturated switching mode with DC current gain (h_FE) of 25–50 at I_C = 10 A and V_CE = 2 V. Its base-emitter turn-on voltage is 0.9 V, and saturation voltage remains ≤370 mV under pulsed conditions (tp ≤ 300 µs, δ ≤ 0.02).

Thermal design is enabled by three distinct R_th(j-a) values: 100 K/W (standard FR4), 41 K/W (6 cm² collector pad), and 30 K/W (Al₂O₃ ceramic PCB), plus a low 6 K/W R_th(j-mb) to mounting base - confirming its suitability for direct heatsink attachment in high-power industrial modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	100 V - Supports 48 V and 60 V automotive bus systems with margin for transients.
I_C	10 A continuous - Enables direct control of medium-power loads (e.g., 12 V/120 W solenoids or fans) without external driver staging.
R_CEsat	25–37 mΩ - Minimizes conduction loss (≤370 mW at 10 A), reducing thermal stress in compact PCB layouts.
T_j max	175 °C - Allows operation in under-hood environments and sealed industrial enclosures without forced cooling.
AEC-Q101	Qualified - Validated for automotive applications including motor control, body electronics, and lighting modules.
Package	SOT669 (LFPAK56) - Exposed mounting base improves thermal transfer; 4-pin SMD footprint replaces DPAK with reduced PCB area.
h_FE	25–50 at I_C = 10 A - Enables stable base drive design with ~1 A I_B, supporting discrete gate driver simplicity.

Pinout & Package

PHPT61010NYX uses the LFPAK56 (SOT669) package: a 4-lead surface-mount plastic power package with an exposed copper mounting base for enhanced thermal conduction. The package measures 5.8 × 4.4 × 1.0 mm and features gull-wing leads compatible with standard reflow soldering profiles.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Emitter (E)	Three parallel emitter terminals reduce bond wire inductance and improve current sharing in high-di/dt switching.
4	Base (B)	Single dedicated base connection optimized for low-inductance drive; requires ~1 A I_B for full saturation at 10 A I_C.
Mounting Base (mb)	Collector (C)	Exposed copper collector terminal serves as primary thermal path and electrical connection - must be soldered to large copper pour or heatsink.

Key Features

Feature	Design Value
High thermal dissipation	25 W P_tot on ceramic PCB enables >10 W continuous dissipation in space-constrained industrial modules.
Reduced PCB footprint	LFPAK56 occupies ~40% less board area than DPAK while delivering superior thermal performance.
High-temperature operation	Rated up to 175 °C T_j supports use in engine bay, power inverters, and sealed LED drivers without derating.
Low R_CEsat	25–37 mΩ ensures <0.4 V drop at 10 A, minimizing self-heating and improving system efficiency over legacy TO-220 devices.
AEC-Q101 qualification	Validated for automotive-grade reliability including HTGB, HTRB, and ESD testing - suitable for safety-critical non-safety functions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-power NPN switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PHPT61010PY	PNP complement with identical V_CEO, I_C, R_CEsat, and package - not electrically interchangeable.	Used in high-side switching configurations where NPN cannot be directly substituted due to polarity constraints.	Select only when complementary high-side control is required in H-bridge or dual-rail designs.
BUK9Y10-100B	100 V, 10 A N-channel TrenchMOS with 11.5 mΩ R_DS(on); logic-level gate; no base current required.	Enables simpler drive circuitry and lower gate charge, but lacks bipolar linearity for analog regulation.	Prefer for pure switching applications; avoid where linear-mode operation or precise V_BE tracking is needed.

Compared with PHPT61010NYX, PHPT61010PY provides matched thermal and electrical specs in PNP topology for complementary circuits, while BUK9Y10-100B offers lower on-resistance and zero gate current but forfeits linear-mode precision and bipolar thermal stability.

FAQ

What is the maximum continuous collector current for PHPT61010NYX?

The PHPT61010NYX is rated for 10 A continuous collector current (I_C) at T_amb ≤ 25 °C with appropriate PCB copper area. Derating applies above ambient: e.g., ~6.5 A at 100 °C ambient on a 6 cm² FR4 collector pad per the published thermal curves.

Can PHPT61010NYX be used in linear (analog) regulation mode?

Yes - its specified V_CEsat (250–370 mV), stable h_FE (25–50 at 10 A), and 175 °C T_j rating make it suitable for linear-mode voltage or current regulation, particularly in automotive LED drivers and precision industrial supplies where bipolar linearity and thermal stability are advantageous.

How does the LFPAK56 (SOT669) package improve thermal performance over DPAK?

The LFPAK56 exposes the collector as a large copper mounting base directly soldered to PCB copper, achieving R_th(j-mb) = 6 K/W - significantly lower than DPAK's typical 15–20 K/W. This allows up to 25 W total power dissipation on ceramic PCB versus ~15 W for DPAK under identical conditions.

Is PHPT61010NYX pin-compatible with other LFPAK56 transistors?

Yes - all LFPAK56 (SOT669) devices share identical mechanical footprint, pad layout, and 4-pin configuration (E-E-E-B with collector base). However, electrical compatibility depends on polarity (NPN vs PNP), voltage/current ratings, and gain characteristics; PHPT61010PY is its direct PNP complement with identical pinout.
